There is no consensus on whether and when surgical treatment is indicated for combined hamartoma of the retina and retinal pigment epithelium (CHRRPE). We aim to discuss the benefits of surgical intervention and techniques that may improve the outcome. A 24-year-old man experienced progressive visual loss for 6 months in his left eye due to CHRRPE. At presentation, visual acuity was 1.3 LogMAR and fundoscopy revealed extensive tractional pre- and epiretinal membranes, subretinal exudation, and a vasoproliferative tumor in the inferior periphery. A complete vitrectomy was performed, while paying special attention to vitreous shaving at the vitreous base and removal of vitreoschisis-induced vitreous cortex remnants (VCR) from the retinal surface posterior to the vitreous base. Tractional membranes and internal limiting membrane were peeled, and the vasoproliferative tumor was excised. Silicone oil tamponade was removed 11 weeks after surgery. No intra- or postoperative complications occurred. Visual acuity improved to 0.8 LogMAR and remained stable for 48-month follow-up. Vitreoretinal surgery can prevent complications that occur with CHRRPE. In addition, visual function may improve even if the initial visual acuity is low. Timely and complete vitrectomy with extensive membranectomy and detection and removal of VCR is recommended to avoid complications in challenging CHRRPE.

The Ideal

The contrast agents in vitreoretinal surgery are necessary to ensure the visualization of translucent and ultra-thin membranes and vitreoretinal interface (VRI) structures, but the ideal staining agent has not been found yet.Purpose. To investigate and compare staining properties of two vital dyes for vitreous body (VB) and vitreoretinal interface visualization: “Kenalog-40” and “Vitreocontrast”.Patients and methods. The study was performed on 20 cadaveric eyes. After eyeball dissection with the original technology, we carried out posterior vitreous cortex separation and comparative staining of retinal fragments on the side of VB and corresponding section of the VB by “Kenalog-40” and “Vitreokontrast”. Vitreo-retinal interface samples underwent morphological analysis.Results. In contrast to «Kenalog-40», «Vitreocontrast» enables the visualization of thin layer of VB on retina surface after splitting of cortical layers during posterior vitreous detachment induction. Upon that, the adherent particles of the “Vitreocontrast” suspension remained on the corresponding splitted fragment of the VB. After staining with “Kenalog-40”, the VB surface remained smooth, shiny, with no visible changes. The results of histological examination of the obtained retinal and VB samples confirmed the presence of VB layer on the retina surface at the site of vitreoshisis formation during the induction of posterior vitreous detachment.Conclutions. Received data confirm the possibility of vitreoshisis formation during posterior vitreous body detachment, and demonstrate the advantages of the staining properties of the “Vitreokontrast” suspension for visualization of fine structures of vitreoretinal interface.

Vitreomacular Interface

Retinal defects evolving whole neural layers in the macular area especially in the fovea are being called macular hole (idiopathic macular hole; IMH). It causes painless central visual loss and deterioration of vision that is called metamorphopsia. Antero-posterior dynamic forces (vitreomacular traction; VMT) caused by tangential tractional vectors of the prefoveal vitreous cortex and progression to full-thickness macular hole due to weakening of the inner retinal layers are attributed for the etiology of macular hole. IMH is seen frequently unilaterally in females and patients > 65 years of age. An approach for IMH treatment, aiming to release the traction and closure of the macular hole by pharmacological vitreolysis is the use of ocriplasmin, which is a plasmin derivative. To release the synechia on the vitreomacular interface and to normalize the abnormalities of the retinal surface are the aims of IMH surgery. Besides, vitreoretinal surgery constitutes suitable conditions for the closure of the hole. Separation and detachment of the posterior hyaloid, core vitrectomy, removal of the peripheral vitreous, and Internal Limiting Membran (ILM) peeling are the standard stages of the classic IMH surgery. Condition of the other eye, presence of Epiretinal Membran (ERM), hole width, patient's age, and quality of life are important factors when evaluating the patients. Ocriplasmin alternative must be kept in mind in holes smaller than 400 μ especially if VMT is existent. IMH is such a pathology that can be treated successfully by vitrectomy and ILM peeling at the present situation.

Open Globe Injuries

Purpose: To investigate the possible risk factors and prognosis of initial no light perception (NLP) in pediatric open globe injuries (POGI). Procedures: This retrospective, comparative, interventional case-control study included 865 eyes of POGI patients presenting to a tertiary referral ophthalmic center from 1 January 2011 to 31 December 2015. Eyes were divided into two groups: NLP group included eyes with initial NLP, and light perception(LP) group included eyes with initial LP or vision better than LP. Results: The following risk factors were significantly related to initial NLP: severe intraocular hemorrhage (OR=3.287, p=0.015), retinal detachment (RD) (OR=2.527, p=0.007), choroidal damage (OR=2.680, p=0.016) and endophthalmitis (OR=4.221, p＜0.001). Choroidal damage is related to remaining NLP after vitreoretinal surgery (OR=12.384, p=0.003). At the last visit, more eyes in the NLP group suffered from silicone oil–sustained status (OR=0.266, p=0.020) or ocular atrophy (OR=0.640, p=0.004), and less eyes benefitted from final LP (OR=41.061, p＜0.001) and anatomic success (OR=4.515, p＜0.001). Conclusion: Severe intraocular hemorrhage, RD, choroidal damage and endophthalmitis occurred more often in POGI with initial NLP. Choroidal damage was the major factor related to an NLP prognosis. Traumatized eyes with initial NLP could be anatomically and functionally preserved by vitreoretinal surgery.
