Changes in the scotopic electroretinogram (ERG) and oscillatory potentials (Ops) were examined in patients who had rhegmatogenous retinal detachment within 3 days before and also at regular intervals after a successful reattachment operation. Electroretinograms were recorded in 38 patients (age 10 to 62 years) for the recent 5 year period. The amplitudes of the scotopic a-wave and b-wave in the detached eye were significantly decreased compared to the fellow normal eye preoperatively. Statistically significant differences were found between the preoperative and the postoperative recordings of the diseased eye. However, postoperative interocular differences in the amplitude of the a-wave between the reattached and normal fellow eye were not statistically significant. The amplitudes of the a-wave and b-wave were inversely related to the extent of the retinal detachment area, the duration of the detachment, and the extent of the buckles that were applied. Significant interocular differences in the b/a wave amplitude ratio and the Ops amplitude were observed. These results strongly suggest that the retinal function, even after successful reattachment surgery, might be compromised mainly by an inner retinal malfunction rather than from a photoreceptor dysfunction.

PURPOSE: To report a case of acute angle-closure glaucoma resulting from spontaneous hemorrhagic retinal detachment. METHODS: An 81-year-old woman visited our emergency room for severe ocular pain and vision loss in her left eye. Her intraocular pressures (IOPs) were 14 mmHg in the right eye and 58 mmHg in the left eye. Her visual acuity was 0.4 in the right eye but she had no light perception in the left eye. The left anterior chamber depth was shallow and gonioscopy of the left eye showed a closed angle. In comparison, the right anterior chamber depth was normal and showed a wide, open angle. Computed tomography and ultrasonography demonstrated retinal detachment due to subretinal hemorrhage. After systemic and topical antiglaucoma medications failed to relieve her intractable severe ocular pain, she underwent enucleation. RESULTS: The ocular pathology specimen showed that a large subretinal hemorrhage caused retinal detachment and pushed displaced the lens-iris diaphragm, resulting in secondary angle-closure glaucoma. CONCLUSIONS: Prolonged anticoagulant therapy may cause hemorrhagic retinal detachment and secondary angle-closure glaucoma. If medical therapy fails to relieve pain or if there is suspicion of an intraocular tumor, enucleation should be considered as a therapeutic option.

PURPOSE: To describe early macular hole (MH) development in rhegmatogenous retinal detachment (RRD) after scleral buckling (SB) based on optical coherence tomography (OCT) findings. METHODS: The medical records and spectral domain OCT images of patients in whom MH developed after RRD repair were evaluated retrospectively. RESULTS: A postoperative MH was detected in five eyes that underwent SB during a 6-year period. All had fovea-off RRD without MH at the time of surgery. OCT showed partial loss of the inner retina with a preserved photoreceptor layer in early postoperative days. On average, 7 days (range,5 to 8 days) after surgery, outer retinal tissues disappeared, resulting in the full-thickness MH. CONCLUSIONS: Serial OCT findings revealed that partial-thickness lamellar holes progressed to full-thickness MHs, which were formed by the degeneration of the outer retina in eyes with preceding loss of the glial cone in the fovea.

A 28-year-old female presented with a palpable mass lesion on the superonasal aspect of her right globe and she had a progressive diplopia. She had a scleral encircling surgery with a Miragel explant (MIRA, Waltham, Mass, USA) for the tractional retinal detachment associated with pars planitis 9 years previously. On examination, she revealed restricted eye movements of her right eye. The magnetic resonance imaging documented a swelling of the Miragel explant that mimicked a periorbital mass lesion. The Miragel explant was removed and fragmentation of the explant was found intraoperatively. The removed Miragel explant was examined by a scanning electron microscopy, and this demonstrated a disintergrated and swollen structural composition of the Miragel explant. Postoperatively, her extraocular movement was almost restored and the retina remained well attached. Alterations in the structural composition of the Miragel explant results in an excessive swelling that causes a restriction of the extraocular movement, and this can mimick a periorbital mass lesion.

PURPOSE: To evaluate the usefulness of OCT retinal mapping in determining the configuration of a vitreomacular adhesion and selecting a meridian for entry into the subhyaloid space in patients with vitreomacular traction syndrome. METHODS: Six consecutive patients (6 eyes) with vitreomacular traction syndrome underwent vitrectomy with peeling of posterior hyaloid. Ocular coherence tomography (OCT) retinal mapping was performed preoperatively. Access to the subhyaloid space was made by creating an opening with a 25 gauge needle at a location where the detached posterior hyaloid membrane was farthest from the retinal surface. The location was selected based on six preoperative meridional OCT scans. The posterior hyaloid was then gently peeled off in a circular fashion around the fovea with a micropick. Visual acuity and foveal thicknesses were measured before the operation and 3 months afterwards. RESULTS: After the operation, visual acuity improved and central macular thicknesses were reduced significantly in all six patients. The best corrected visual acuity improved from 0.4 to 0.75 with a mean increase by 3.5 lines on a Snellen chart 3 months after the operation. The mean foveal thickness was reduced from 406 micrometer to 241 micrometer. The restoration of foveal pit was observed in five patients. Neither intraoperative nor postoperative complications were observed during the follow up period. CONCLUSIONS: An OCT retinal mapping program is a valuable diagnostic tool in understanding the configuration of vitreomacular adhesion and planning the surgical approach for operating on vitreomacular traction syndrome.

We retrospectively evaluated the clinical characteristics and surgical outcomes of 20 pseudophakic retinal detachment (RD) patients (20 eyes) and 17 aphakic RD patients (17 eyes). Males were predominated in both groups. The time interval between cataract extraction and RD was 31 months on average in the pseudophakic group, 32 months with intact posterior capsule and 27 months with ruptured posterior capsule, and 148 months in the aphakic group. In 50% of cases with ruptured posterior capsule in the pseudophakic group, RD occurred within 1 year. The anatomic success rate was 95% in the pseudophakic group and 88% in the aphakic group. The most common cause of failure was the development of proliferative vitreoretinopathy. Visual acuities more than 20/40 after RD surgery were found in 13 pseudophakic (65%) and 6 aphakic (36%) eyes. Aphakic patients were more inclined to have silent RD than pseudophakic patients because of their poor visual acuity. Post-operative follow-up is required especially for the first 1 year in cases of damaged posterior capsule due to the high incidence of RD during this period.
