1.A Case of Full-thickness Macular Hole Formation Secondary to Laser Retinopexy
Journal of the Korean Ophthalmological Society 2023;64(6):545-549
Purpose:
To report a case of full-thickness macular hole (FTMH) formation secondary to demarcation laser retinopexy in a retinal break with localized retinal detachment patient.Case summary: A 59-year-old male visited our clinic with ocular discomfort in both eyes. Uncorrected visual acuity (UCVA) was 0.63 in right eye. Large retinal break in 1:30 o/c, localized retinal detachment and laser marking scars all around the right eye were found in fundoscopic exam. Posterior-vitreous detachment or vitreomacular traction was not observed in optical coherence tomography (OCT). Demarcation laser retinopexy was performed around the margin of retinal detachment and peripheral degenerative lesions. Three months after demarcation laser retinopexy, UCVA in right eye of the patient was decreased to 0.16 and full thickness macular hole was observed on OCT examination. Pars planar vitrectomy, internal limiting membrane peeling, and SF6 gas tamponade were performed in the right eye. One month after the surgery, closure of FTMH was observed. Three months after surgery, there were no recurrence of FTMH in the right eye.
Conclusions
Demarcation laser photocoagulation of localized retinal detachments may predispose to FTMH formation. Even though it can be occurred rarely, follow-up check-up is necessary in consideration of the possibility of FTMH, which can cause serious visual loss.

PURPOSE: To present a rare case of Muir-Torre syndrome characterized by the association of sebaceous skin tumors and systemic malignancies. CASE SUMMARY: A 65-year-old female visited our clinic with an irregular nodular mass of the right lower eyelid, which developed 1 year earlier. An excisional biopsy and lower lid reconstruction with Tenzel's semicircular rotational flap was performed under local anesthesia. Histopathologic examination showed well-differentiated sebaceous cells, consistent with sebaceous adenoma. The patient had undergone total abdominal hysterectomy and lower anterior resection due to endometrial cancer and sigmoid colon cancer 5 years before, and nephroureterectomy due to papillary urothelial carcinoma 3 years before. Based on the history of systemic malignancy and sebaceous skin cancer, a diagnosis of Muir-Torre syndrome was made. CONCLUSIONS: When a sebaceous gland tumor of the eyelids is detected, Muir-Torre syndrome should be included in the differential diagnosis, and systemic work-up for the internal malignancy must be performed.

PURPOSE: To compare the histopathologic and morphologic findings of encapsulated blebs following Ahmed glaucoma valve implantation and primary standard trabeculectomy with mitomycin-C. METHODS: We reviewed the records of patients with otherwise uncontrollable glaucoma who had undergone Ahmed glaucoma valve implantation or trabeculectomy with mitomycin-C. Five eyes that underwent Ahmed valve implantation and three eyes that underwent trabeculectomy needed surgical revision of the initial surgery due to encapsulated bleb development with total loss of function. The surgically removed encapsulated blebs were analyzed macroscopically and microscopically. RESULTS: Removal of the encapsulated bleb was performed at a mean follow-up time of 26.6 +/- 19.4 weeks in the Ahmed valve implantation group and 12.0 +/- 11.4 weeks in the trabeculectomy group. The fibrotic wall of the encapsulated blebs had an overall thickness of 2.48 +/- 0.42 mm in the Ahmed valve implantation group and 1.62 +/- 0.37 mm in the trabeculectomy group. Macroscopically, the coconut flesh-like smooth surface was split into two layers, and the wall of the capsule was thicker in the Ahmed valve implantation group than in the trabeculectomy group. Histopathologically, the fibrotic capsule was composed of an inner fibrodegenerative layer and an outer fibrovascular layer, and there were no histopathological differences between the two groups. CONCLUSIONS: The fibrotic capsule wall was thicker in the Ahmed valve group, but there were no differences in histological findings between the two groups.

PURPOSE: To report a rare case of Sjögren's reticular retinal dystrophy. CASE SUMMARY: A 54-year-old male presented with blurred vision and metamorphopsia in both eyes since a few years prior to his initial visit. There was a bilateral reticular network of yellow deposits throughout the posterior pole on fundus examination, which was hyperautofluorescent in fundus autofluorescence photographs. The pigment alterations were more visible with fluorescein angiography, which showed hypofluorescent lesions with hyperfluorescent borders. Spectral-domain optical coherence tomography showed elevations of the outer retina associated with the presence of subretinal hyperreflective material. Based on the conclusive correlation with clinical features, we diagnosed Sjögren's reticular retinal dystrophy. CONCLUSIONS: Sjögren's reticular retinal dystrophy is characterized by its specific pigment changes at the level of clinical manifestations and the retinal pigment epithelium. In cases of Sjögren's reticular retinal dystrophy, close monitoring is required because it has a lifetime risk of choroidal neovascularization.

PURPOSE: To report a rare case of traction retinal detachment and retinal ischemia in inactive Takayasu's arteritis at ophthalmologic clinic. CASE SUMMARY: A 23-year-old woman presented with a floater, photophobia, and visual loss in her right eye one week prior to visit. She had no other systemic disease, such as diabetes mellitus or hypertension, or previous ophthalmic abnormalities except for a tumor in the adrenal gland. We found bilateral retinal ischemia and traction retinal detachment in the right eye on fundus examination without iris neovascularization. Pars plana vitrectomy, traction removal, endolaser treatment, and intravitreal bevacizumab injection were performed. Steroid eye drops and steroid systemic administration relieved the inflammation. On carotid doppler sonography, we found severe stenosis and thickness of the inner layer in both carotid arteries. We diagnosed the patient with an inactive phase of Takayasu's arteritis, which was conclusively correlated with the clinical features. Vascular anastomosis surgery along with follow-up was proposed by both the cardiology and vascular surgery departments. CONCLUSIONS: When a young patient presents with traction retinal detachment and retinal ischemia, Takayasu's arteritis should be considered for differential diagnosis and a systemic work-up should be performed as soon as possible.
