A 44-year-old obese woman with a medical history of iron-deficiency anemia (pretreatment hemoglobin of 8.8 g/dL) presented with blurred vision in her right eye and new headaches over 1 month. She described the headaches as holocephalic, rated them 4–5 out of 10 (where 1 is minimal intensity and 10 is maximal intensity) without any diurnal or positional variation. She had associated intermittent nausea, but no vomiting. She denied any characteristics consistent with a thunderclap headache. She initially saw her optometrist and was referred to neuro-ophthalmology for bilateral optic disc edema. Examination revealed a visual acuity of 20/30 OD and 20/20 OS, and Humphrey visual field testing showed an enlarged blind spot OD (MD −4.60 dB) and was normal OS (MD −2.10 dB). Slit-lamp examination revealed a posterior subcapsular cataract in the OD and dilated fundus examination showed moderate optic disc edema in both eyes with hemorrhages in all 3 retinal layers in the OD (shown in Fig. ). Her blood pressure was 128/78, and her hemoglobin was found to be 9.0 g/dL with mean corpuscular volume of 70.4 fL. Magnetic resonance imaging/magnetic resonance venography of the head was normal apart from signs of raised ICP, and lumbar puncture showed an opening pressure of 34 cm of water with normal CSF contents. She was started on acetazolamide 500 mg BID and continued her recent supplementation with ferrous fumarate. With significant weight loss, her optic disc edema resolved after 4 months, and she continued to maintain normal visual function. The final Humphrey mean deviation was −2.80 dB OD and −0.72 dB OS.
A 39-year-old man, complained about a 3-day history of bilateral blurred vision. He had a past medical history of kidney transplantation 5 years ago and was receiving systemic immunosuppressive therapy. The patient was hospitalized for chickenpox and was treated with systemic antivirals 3 weeks prior to ocular symptoms onset. On ophthalmic examination, the patient’s best corrected visual acuity (BCVA) was 20/200 in the right eye (RE) and 20/25 in the left eye (LE). Slit-lamp examination showed stromal keratitis and few fine keratic precipitates in the RE (Fig. ) and 1+ anterior chamber cells in both eyes. Intraocular pressure was 22 mmHg in the RE and 20 mmHg in the LE. There were no vitreous cells, and results of dilated fundus examination were unremarkable in both eyes. The patient was diagnosed with keratouveitis in the RE and acute anterior uveitis in the LE secondary to chickenpox. He was treated with topical acyclovir five times a day, dexamethasone six times a day, beta blockers, and atropine 1% twice daily. He was lost to follow-up. One year later, he presented with a 1-week history of blurry vision bilaterally. On ophthalmic examination, BCVA was 20/200 in the RE and 20/30 in the LE. Slit-lamp examination showed “mutton-fat” pigmented keratic precipitates (Fig. ), 1+ anterior chamber cells, corneal scars, patchy iris atrophy with circumscribed depigmented spots of the iris, and distorted pupil (Fig. ) in both eyes. Intraocular pressure was 27 mmHg in the RE and 24 mmHg in the LE. Assessment of posterior segments revealed no abnormalities in both eyes. A diagnosis of recurrent granulomatous anterior uveitis was made. The patient was treated with topical dexamethasone six times a day, topical acyclovir five times a day, beta blockers, and atropine 1% twice daily. Intraocular inflammation gradually resolved, and visual acuity improved. Topical steroids and acyclovir were slowly tapered. Visual acuity improved to 20/25 in both eyes one month after presentation. No recurrence of intraocular inflammation was observed over a follow-up period of 24 months.
