We report a rare instance of favorable outcome in orbital apex syndrome secondary to herpes zoster ophthalmicus (HZO) in a human immunodeficiency virus (HIV)-positive patient. The patient complained of pain and decrease in vision in one eye (20/640) for 2 weeks accompanied with swelling, inability to open eye, and rashes around the periocular area and forehead. The presence of complete ophthalmoplegia, ptosis, relative afferent pupillary defect, and anterior uveitis with decreased corneal sensation prompted a diagnosis of HZO with orbital apex syndrome. The enzyme-linked immunosorbent assay test and a low CD4 count confirmed HIV. Highly active antiretroviral therapy (HAART), systemic acyclovir, and systemic steroids were started. Visual acuity and uveitis improved within 10 days. By the end of the fourth week, ocular motility also recovered and the final visual acuity was 20/25. We highlight the role of HAART, used in conjunction with systemic steroid and acyclovir therapy, in improving the outcome.
The association of macular detachment with posttraumatic macular hole is a known but rare occurrence. Spontaneously occurring resolution of the detachment and closure of the macular hole has been reported only once in the literature. We describe a similar rare event in a young male, the documentation of which was done serially by microperimetry (MP) and optical coherence tomography (OCT). A 17-year-old male presented with a decrease in vision following a closed globe injury to the left eye. A coexisting macular hole and macular detachment were detected in the affected eye. Serial follow-up with OCT and MP documented complete resolution of the macular hole and the macular detachment within 1 week of presentation. The case highlights that spontaneous resolution of traumatic macular hole and related macular detachment may occur and a waiting period is advisable before undertaking any corrective surgical procedure. The pathophysiologic mechanisms of causation and the resolution of posttraumatic macular hole-related retinal detachment are discussed.
Purpose:
To evaluate the central visual field by microperimetry (MP), in early glaucoma.
Methods:
Consecutive perimetrically experienced patients with a single nasal step or arcuate scotoma and 14 control eyes underwent MP. Retinal sensitivity on MP was mapped for frequency and depth of loss in the central 10° around fixation.
Results:
Twenty-one eyes had a single nasal step and 19 eyes with single arcuate scotoma on standard automated perimetry (SAP), with central 10° being normal on 30–2 and 10–2 perimetry. The average mean sensitivity on MP, in glaucomatous and control eyes was 11.8 ± 3.9 dB and 16.6 ± 1.2 dB, respectively,
P
= 0.0004. The average mean defect on MP-1, in glaucomatous and control eyes was - 6.5 ± 2.0 dB and - 3.0 ± 1.2 Db, respectively,
P
= 0.05. The corresponding retinal hemisphere showed significant defects in MP. In eyes with single nasal steps, an absolute scotoma was seen in 14–28% of eyes 8–10° off fixation, moderate to mild defects were seen in 10–52% eyes, and 10% eyes showed involvement up to 4° from the fixation. Eyes with arcuate scotoma had an absolute scotoma on MP in 95% of eyes, 6–10° from fixation, with extension up to 2° from fixation in 21%. In glaucomatous eyes, the normal hemisphere on SAP showed a mild defect on MP in 43%. Control eyes did not show any defect in SAP or MP.
Conclusion:
A significant loss of central retinal sensitivity is recorded on MP in early glaucomatous neuropathy as compared to SAP. Paramacular absolute defects were seen at 6–10° from fixation.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
