Purpose: To report the explantation of a detached and opaque donor disc as an alternative to secondary keratoplasty in a case of persistent graft detachment followed by spontaneous clearance of the recipient cornea after non-Descemet stripping automated endothelial keratoplasty (non-DSAEK). Methods: A 57-year-old man with cataract and bullous keratopathy after herpes simplex virus endotheliitis of the right eye and best spectacle-corrected visual acuity (BSCVA) of 0.1 underwent simultaneous phacoemulsification and non-DSAEK. Due to early detachment of the donor disc, two additional intracameral air injections were necessary in order to achieve graft attachment. However, the donor disc gradually detached and became fibrotic while the recipient cornea anterior to the detached graft became transparent and without any edema. Therefore, a mere explantation of the DSAEK graft was performed. Results: Four months after graft explantation, BSCVA was 0.5 and endothelial cell density (ECD) was 1,221 cells/mm2. After 13 months, BSCVA was still 0.6 while ECD had fell to 800, and 2 years later, the endothelium decompensated. BSCVA was 0.3 and ECD was not measurable. Conclusions: To our knowledge this is the first report of explantation of an endothelial graft as an alternative to re-keratoplasty in a case of spontaneous corneal clearance. This minimally invasive treatment may be considered in similar cases. However, due to the ongoing loss of endothelial cells after endothelial keratoplasty, a re-keratoplasty may still be needed in the long term.

Purpose: To report the 2-year follow-up findings in a patient with buphthalmic bullous keratopathy (BK) who was successfully treated with non-Descemet stripping automated endothelial keratoplasty (nDSAEK). Methods: A 39-year-old man had an endothelial graft of 8.0 mm diameter placed uneventfully using the nDSAEK method for phakic BK with buphthalmos of the left eye. He had had a penetrating keratoplasty in the right eye due to aphakic BK 5 years earlier, which, however, resulted in the invasion of blood vessels and graft failure. Since the left eye was phakic, Descemetorhexis was not performed because the instruments might touch the crystalline lens. The best-corrected visual acuity (BCVA), intraocular pressure (IOP), and endothelial cell density (ECD) were determined at 2 weeks, and at 1, 3, 6, 12, 18 and 24 months after nDSAEK. Results: Twenty-four months after nDSAEK, his left cornea and lens remained clear, and the decimal BCVA was 0.8. However, the ECD of the graft had decreased from 2,274 cells/mm2 before nDSAEK to 539 cells/mm2 24 months after the surgery, and the rate of decrease appeared to be slightly faster than that of former reports. An IOP of >30 mm Hg was recorded at around 2 months after the surgery, but was well controlled by tapering the topical steroids and the addition of topical brinzolamide and latanoprost. Conclusion: Our findings show that nDSAEK can be successfully used to treat buphthalmic BK. We recommend that nDSAEK be considered especially in phakic eyes with a smooth posterior surface around the pupillary area.

ObjectiveTo compare clinical outcomes and complications between pre-loaded ultra-thin Descemet stripping automated endothelialkeratoplasty (pl-UT-DSAEK) and pre-loaded Descemet membrane endothelial keratoplasty (pl-DMEK).Methods and analysisComparative study in patients with endothelial dysfunction associated with Fuchs endothelial corneal dystrophy and pseudophakic bullous keratopathy who underwent pl-UT-DSAEK or pl-DMEK transplants. For both groups, the tissues were pre-loaded at the Fondazione Banca degli Occhi del Veneto (Venice, Italy) and shipped to The Royal Liverpool University Hospital (Liverpool, UK). Best corrected visual acuity (BCVA) and re-bubbling rates were the main outcome measures.Results56 eyes of 56 patients were included. 31 received pl-UT-DSAEK and 25 received pl-DMEK. At 12 months, BCVA (LogMAR) was significantly better for pl-DMEK (0.17±0.20 LogMAR) compared with pl-UT-DSAEK (0.37±0.37 LogMAR, p<0.01). The percentage of people that achieved ≥20/30 was significantly higher in the pl-DMEK group. The rate of re-bubbling, however, was significantly higher for pl-DMEK (44.0%) than for Pl-UT-DSAEK (12.9%), p<0.01.ConclusionPl-DMEK offers better BCVA than pl-UT-DSAEK. The higher re-bubbling rate associated with pre-loaded DMEK is of concern.

Aims: To evaluate both donor and recipient features involved in visual acuity restoring and complication insurgence in eyes that have undergone Descemet stripping automated endothelial keratoplasty (DSAEK).Methods: In this retrospective study, charts of 111 eyes of 96 patients (mean age 70.25 ± 8.58 years) that underwent DSAEK were evaluated. Only Fuch's Distrophy (FD) or Bullous Keratopathy (BK) due to cataract surgery eyes were included. A complete ophthalmic check with endothelial cell density (ECD) and central corneal thickness (CCT) measurement was performed before surgery and at 1, 3, 6, and 12 months follow-up. Each DSAEK was performed by the same well-trained surgeon; only pre-cut lenticules, provided by same Eye Bank, were implanted.Results: A total of 48 (43%) complications have been observed (most of them were 22 partial graft detachments and 17 IOP spikes). At the last follow-up (mean: 8.58 ± 4.09 months), a significant increase (p &lt; 0.05) of best corrected visual acuity (BCVA) was detected. Overall mean BCVA of the eyes evaluated was 0.40 ± 0.43 LogMAR with BK eyes showing a significantly higher improvement (p &lt; 0.05) compared to FD eyes. The only factor showing a significant correlation (p &lt; 0.05) with visual acuity enhancement was the implant of a lenticule thinner than 100 μm. Recipient features significantly (p &lt; 0.05) associated with complications observed after surgery were glaucoma and diabetes mellitus.Conclusion: The use of a graft thinner than 100 μm can provide better visual acuity recovery while recipients affected by glaucoma or diabetes mellitus are more prone to develop complications after surgery.

History Of

A 65-year-old patient with history of keratoconus, mild cataract and penetrating keratoplasty over 30 years ago developed corneal oedema subsequent of graft failure with best corrected visual acuity (BCVA) of counting fingers. He underwent a successful cataract surgery combined with a 7.25 mm Descemet’s Membrane Endothelial Keratoplasty (DMEK) with Sodium Hexafluoride (SF6) gas. His cornea remained oedematous inferiorly at 4 weeks, despite two subsequent re-bubbling due to persistent DMEK detachment inferiorly. This was managed by three radial full thickness 10-0 nylon sutures placed in the inferior cornea along with intracameral injection of air. Following this, his anterior segment ocular coherence tomography (OCT) confirmed complete attachment of the graft, and the sutures were removed 4 weeks later. Unaided visual acuity was 20/63 and BCVA was 20/32 after 8 months. DMEK suturing can be helpful in persistent DMEK detachments, which is refractory to repeated re-bubbling due to uneven posterior surface of previous PK.

The purpose of this report is to describe a case of bilateral foveal hypoplasia in the absence of other ophthalmological or systemic manifestations. We characterize the case of a 9-year-old Caucasian male who underwent full ophthalmologic examination, including functional measures of vision and structural measurements of the eye. Best corrected visual acuity was 0.50 logMAR in the right eye and 0.40 logMAR in the left eye. Ophthalmoscopy revealed a lack of foveal reflex that was further investigated. Optical coherence tomography (OCT) confirmed the absence of foveal depression (pit). OCT images demonstrated the abnormal structure of retina in a region in which we expected a fovea; these findings were decisive to determine the cause of reduced acuity in the child.

AimTo describe the long-term outcomes of Descemet stripping automated endothelial keratoplasty (DSAEK) with an anterior chamber intraocular lens (ACIOL) compared to secondary posterior chamber (PC) IOL.MethodsThis was a retrospective comparative cohort study. The clinical data of 82 eyes from 82 consecutive patients with pseudophakic (PBK) or aphakic bullous keratopathy (ABK) who either underwent DSAEK with retained or secondary ACIOL (n=23) or DSAEK with IOL exchange and/or secondary PCIOL (retropupillary iris-claw IOL, n=25; intrascleral-fixated IOL, n=29; or sulcus IOL, n=5) were analysed. The main outcome measures were graft survival and complications up to 5 years.ResultsThe graft survival in the secondary PCIOL group was superior than the ACIOL group over 5 years (year 1, 100.0% vs 100.0%; year 3, 94.7% vs 75.0%; year 5, 91.1% vs 60.6%, p=0.022). The presence of an ACIOL was a significant risk factor associated with graft failure (HR, 4.801; 95% CI, 1.406 to 16.396, p=0.012) compared to a secondary PCIOL. There was no significant difference in the rate of graft detachment and elevated intraocular pressure between the groups. There were five cases (9.3%) of IOL subluxation or dislocation in the retropupillary iris-claw and intrascleral-fixated IOL groups.ConclusionsEyes that underwent DSAEK with ACIOL in situ had poorer long-term graft survival compared with those with secondary PCIOL. Intraocular lens exchange was not associated with a higher complication rate. In ABK or PBK eyes with ACIOL, we recommend performing IOL exchange and/or secondary PCIOL implantation combined with endothelial keratoplasty.

Purpose: To report the morphological and clinical features of a case of pachychoroid disease with focal choroidal excavation and large choroidal excavation complicated by choroidal neovascularization. Methods: The patient underwent a complete ophthalmologic examination including best-corrected visual acuity assessment, anterior segment and dilated fundus examination, fluorescein and indocyanine green angiography, and spectral-domain optical coherence tomography. Results: During the previous follow-up, the 57-year-old man received a diagnosis of central serous chorioretinopathy in the right eye with a late appearance of a choroidal neovascularization. The best-corrected visual acuity was 20/125 and 20/20 in the right and left eye, respectively. Dilated fundus examination, fluorescein angiography, and indocyanine green angiography confirmed a large subretinal fibrosis corresponding to the evolution of the choroidal neovascularization in the right eye. Spectral-domain optical coherence tomography clearly demonstrated in the right eye a large choroidal excavation below the fibrotic neovascular lesion with multiple hyperreflective foci inside the cavity, and in the left eye, a conforming focal choroidal excavation, bowl-shape type, associated with increased choroidal thickness with pachyvessels. Conclusion: Large choroidal excavation has been rarely reported. Although the pathogenetic mechanisms leading to the formation of large choroidal excavation are still only hypotheses, a combination of primary degenerative inflammatory factors sustaining the focal choroidal excavation formation and disruptive process of the choroidal neovascularization could be retained responsible for the large choroidal excavation.

The objective of this study was to present an unusual low velocity transorbital penetrating injury. The study design was a clinical record (case report). A 38-year-old gentleman tripped and fell face first onto the wing of an ornamental brass eagle. This penetrated the inferomedial aspect of the right orbit, breaching the lamina papyracea to extend into the ethmoid sinuses and reaching the dura of the anterior cranial fossa. The foreign body was removed in theater under a joint ophthalmology and ENT procedure. The patient was left with reduced visual acuity in the right eye but no other long-term sequelae. Transorbital penetrating injury presents unusual challenges to investigation and management requiring a multidisciplinary approach to prevent significant morbidity and mortality. If managed well the prognosis is good.

Introduction. To report a case of anterior sclera staphyloma and vitreous hemorrhage occurring over 38 years after bilateral cataract surgery.Methods. A 58-year-old man presented with anterior sclera staphyloma and vitreous hemorrhage in the right eye, after bilateral cataract surgery, over 38 years ago. We performed combined anterior sclera staphylectomy and vitrectomy of right eye for anterior sclera staphyloma and vitreous hemorrhage.Results. Forty-eight months after the combined surgery, best-corrected visual acuity was 0.3 (+10.00/−4.50 × 60) with eutopic stitches of the corneoscleral junction on the superior nasal quadrant and a stable ocular surface.Conclusions. This is the first reported case of anterior sclera staphyloma with vitreous hemorrhage successfully managed by combined surgery.
