Resolution of Combined Hamartoma of Retina And Retinal Pigment Epithelium (CHRRPE) with Following Pars Plana Vitrectomy

ABSTRACT: PRE AND POST OPERATION OF VITRECTOMIC PARS PLANE FOR ABLASIO RETINA PATIENTS AT PERTAMINA HOSPITAL BINTANG AMIN BANDAR LAMPUNG Background :Retinal detachment is a condition in which the sensory parts of the retina (photoreceptors and deep tissue layers) and the retinal pigment epithelium (RPE) are separated (Budhiastra, 2016). the world, which is 1 in 10,000 population. And the average age of 40-70 years is the most susceptible to retinal detachment. This prevalence can increase if the patient with retinal detachment has several other conditions such as aphaxia / pseudophakia, high myopia and trauma. in young people they are more likely to experience retinal detachment caused by trauma, and in people aged 25-45 years, retinal detachment is more common due to high myopia. Purpose: The purpose of this study was to determine the sharp vision of pre and post pars plana vitrectomy patients with retinal detachment at Pertamina Bintang Amin Hospital in Bandar Lampung in 2020. Result : The results of 60 respondents with visual acuity from retinal detachment patients who successfully increased were 47 respondents with a percentage (78.3%) and 13 respondents with retinal detachment who did not improve were 13 respondents with a percentage (21.7%) and retinal detachment patients with retinal detachments were found. As many as 49 respondents managed to attach with a percentage (81.7%) for retinal detachment patients whose retina failed to adhere, 11 respondents (18.3%) were found. Conclusion : There is a significant difference between pre and post-operative Pars Plana Vitrectomy in patients with retinal detachment Keywords: Retinal Detachment, Pars Plana Vitrectomy, Sharp Eyesight INTISARI : TAJAM PENGLIHATAN PRA DAN PASCA OPERASI PARS PLANA VITREKTOMI PADA PASIEN ABLASIO RETINA DI RUMAH SAKIT PERTAMINA BINTANG AMIN BANDAR LAMPUNG TAHUN 2020 Pendahuluan: Ablasio retina adalah keadaan dimana bagian sensoris retina (fotoreseptor dan lapisan jaringan dalam) dan retinal pigment epithelium (RPE) menjadi terpisah (Budhiastra, 2016) Ablasi retina bisa diartikan juga terpisahnya sel kerucut dan batang retina dari sel epitel pigmen retina, Prevalensi ablasio retina di dunia yaitu sebanyak 1 berbanding 10.000 populasi. Dan rata-rata usia 40-70 tahun adalah yang paling rentan terkena ablasio retina. Prevalensi tersebut bisa meningkat jika penderita ablasio retina tersebut memiliki beberapa keadaan lain seperti afaksia/pseudofakia, myopi tinggi dan trauma. pada orang muda mereka lebih sering mengalami ablasio retina yang disebabkan oleh trauma, serta pada orang berusia usia 25-45 tahun ablasio retina lebih sering terjadi dikarenakan myopia tinggi.Tujuan : Tujuan dari penelitian ini adalah untuk mengetahui Tajam Penglihatan pasien ablasio retina pra dan pasca operasi pars plana vitrektomi di Rumah sakit Pertamina Bintang Amin Bandar Lampung tahun 2020.Hasil : Hasil dari 60 responden tajam penglihatan dari pasien ablasio retina yang berhasil meningkat didapatkan responden sebanyak 47 orang dengan persentase (78.3%) dan tajam penglihatan pasien ablasio retina yang tidak meningkat didapatkan sebanyak 13 reponden dengan persentase (21.7%) dan didapatkan pasien ablasio retina yang retina berhasil menempel sebanyak 49 responden dengan persentase (81.7%) untuk pasien ablasio retina yang retina gagal menempel didapatkan responden sebanyak 11 dengan persentase (18.3%). Kesimpulan : Terdapat perbedaan yang cukup signifikan dari tajam penglihatan pra dan pasca Operasi Pars Plana Vitrektomi pada pasien Ablasio Retina Kata kunci : Ablasio Retina, Pars Plana Vitrektomi, Tajam Penglihatan

Purpose Macular translocation has been proposed as an alternative technique in the treatment of some cases of choroidal neovascularization. The purpose of the paper is to report the histopathologic findings in the retina of swine eyes undergone macular translocation. Methods Ten eyes of ten Yucatan pigs underwent posterior pars plana vitrectomy and scleral imbrication to achieve macular translocation. Mattress sutures were preplaced at the equator of the eyes. After a pars plana vitrectomy, balanced saline solution was injected under the temporal retina to produce a retinal detachment. Scleral imbrication was achieved by tightening the mattress sutures. An air-fluid exchange was performed and the eye was filled with sulfur hexafluoride 18%. The eyes were enucleated 2, 4, 8 and 12 weeks after surgery and analyzed under light and electron microscopy. Results Macular translocation was achieved in all cases. The major findings consist of a minimal decrease in the number of photoreceptors outer segments; also a change in the morphology was noted. This included some degree of loss of vertical alignment and an increase in the interphotoreceptor space. There was a recovery in the morphology of the photoreceptors over time. Conclusions Minimal changes in the photoreceptors and retinal pigment epithelium are observed when macular translocation is performed with recovery of these changes over time. Scleral imbrication is an effective technique to achieve translocation of the fovea.

Intraoperative Oct

We report a case of a 7-year-old boy with neurofibromatosis 2 who was referred to our pediatric retina clinic for deteriorating vision of his left eye. Fundoscopy revealed a gray epiretinal and vitreous opacity extending to the fovea in the left eye. Optical coherence tomography (OCT) demonstrated an epiretinal membrane (ERM) with a distinct tissue plane and overlying vitreoretinal strands, consistent with combined hamartoma of the retina and retinal pigment epithelium (CHRRPE). Intraoperative OCT-guided pars plana vitrectomy and membrane peel were performed and the tissue was sent for histopathologic evaluation. Intraoperative scleral-depressed examination also revealed multiple elevated, white-gray, semitranslucent masses near the ora serrata, consistent with astrocytic hamartomas. Histopathologic analysis of the epiretinal tissue revealed glial origin. Recognition of any of these lesions in a young patient should prompt neurologic and genetic evaluation.
