Viruses account for 80% of all cases of acute conjunctivitis and adenovirus; enterovirus and herpes virus are the common causative agents. In general, viral conjunctivitis spreads easily. Therefore, to control the spread, it is crucial to quickly diagnose illnesses, strictly implement hand washing laws, and sanitize surfaces. Swelling of the lid margin and ciliary injection are subjective symptoms, and eye discharge is frequently serofibrinous. Preauricular lymph node swelling can occasionally occur. Approximately 80% of cases of viral conjunctivitis are caused by adenoviruses. Adenoviral conjunctivitis may become a big global concern and may cause a pandemic. Diagnosis of herpes simplex viral conjunctivitis is crucial for using corticosteroid eye solution as a treatment for adenovirus conjunctivitis. Although specific treatments are not always accessible, early diagnosis of viral conjunctivitis may help to alleviate short-term symptoms and avoid long-term consequences.

Purpose This study aimed to report a case of Vogt–Koyanagi–Harada (VKH) disease that recurred 46 years after initial treatment; the recurrence occurred 2 months after the third dose of coronavirus disease 2019 vaccination.Case report: A 59-year-old female patient had bilateral blurring for 2 months; she received her third dose of coronavirus disease 2019 vaccine 4 months before the onset of blurring. The best-corrected visual acuity was 1.0 in the right eye and 0.15 he left eye at the initial visit. Iritis and synechia between lens and iris were observed bilaterally. Sunset glow fundus was found in both eyes with no serous retinal detachments or disk hyperemia. She had a history of VKH disease and was treated with whole-body corticosteroid administration at another hospital when she was 13 years old. She was diagnosed with VKH disease recurrence, and oral corticosteroid intake and corticosteroid eyedrop treatments were initiated. The treatment response was good, but left synechia remained between the lens and iris in the left eye. Recurrence was not observed for 10 months until this study, and her best-corrected visual acuity was 1.0 in both eyes.Conclusion To our knowledge, this case represents the longest recorded interval of VKH disease recurrence in the literature.

Here, two cases involving the oldest reported patients with sympathetic ophthalmia (SO) after non-complicated cataract surgery, are reported. The first case was an 85-year-old female with bilateral decreased vision and headache. The best-corrected visual acuity (BCVA) was 0.8 in the right eye and 1.0 in the left eye at the initial visit. Pseudophakia and choroidal detachments were observed in both eyes, and retinal pigment epithelium undulation was observed by optical coherence tomography. The second case was a 90-year-old male with bilateral optic disc oedema. The BCVA was 0.09 in the right eye and 0.3 in the left eye with pseudophakic eyes. Optic disc oedema and choroidal thickening were observed in both eyes. Both patients were diagnosed with SO, and corticosteroid pulse treatments were started. The BCVA of the first case improved to 0.9 in the right eye and 1.2 in the left eye, while that of the second case reached 0.3 in the right eye and 0.6 in the left eye. No recurrence was observed in either case at 12 months after the initial visit. Both elderly patients with SO were successfully treated.
