Purpose: To identify ocular complications in patients with myelodysplastic syndromes (MDS), who have a propensity to progress to acute myeloid leukemia (AML).
Methods: Forty-one patients with MDS were the subjects in this retrospective study, and 21 patients with AML were selected as controls. Reviewing their clinical records, we verified that corneal ulcer, iridocyclitis, vitreous hemorrhage, retinal hemorrhage, and optic neuritis had been evaluated using slit-lamp assessment and opthalmoscopy in all the patients. In this study, the MDS patients were classified into those with refractory anemia (RA) and those with refractory anemia with excess blasts (RAEB).
Results: Ocular complications were found in 19 (46.3%) of the 41 patients with MDS, comprising corneal ulcer (two cases), iridocyclitis (five), vitreous hemorrhage (one), retinal hemorrhage (ten), cotton wool spots (one), and optic neuritis (two). (Some patients had more than one ocular complication.) Ocular complications were identified in 12 of the 21 (57.1%) patients with AML. There was no significant difference in frequency of ocular complications between MDS and AML (P = 0.4892). In MDS, retinal hemorrhage was associated with significantly reduced platelet counts (P = 0.0063). The frequency of ocular complications was significantly higher in MDS-RAEB than in MDS-RA (P = 0.0478). Retinal hemorrhage was significantly more frequent in patients with MDS-RAEB than in patients with MDS-RA (P = 0.0433).
Conclusion: Ocular complications in MDS patients should be carefully examined as prognostic factors for progression to acute leukemia.

Onchocerciasis is not a major cause of blindness in two endemic villages in Sierra Leone.
BMC Res Notes

Helen Keller International, New York, USA.
Objective: Sierra Leone, a country where onchocerciasis is endemic in 14 of the 16 districts, was the focus of our investigation. Despite 17 rounds of annual ivermectin treatment since 2005, a report circulated by a local politician indicated an increase in cases of suspected onchocerciasis-related vision impairment in two villages (Mangobo and Petifu) in Tonkolili district. In response, the National Neglected Tropical Disease Program conducted a comprehensive investigation.

Herpes zoster Ophthalmicus (HZO) affecting the ophthalmic division (V1) of the trigeminal nerve. HZO may cause extraocular muscle palsies, with the third nerve being the most commonly affected and the fourth nerve the least. The combined involvement of the optic nerve and isolated paralysis of the eye muscle is very rare, with only limited case reports documenting this complication of ocular herpes zoster.

Vision loss affects more than 7 million Americans and impacts quality of life, independence, social functioning, and overall health. Common and dangerous conditions causing sudden vision loss include acute angle-closure glaucoma, retinal detachment, retinal artery occlusion, giant cell arteritis, and optic neuritis. Acute angle-closure glaucoma features ocular pain, headache, and nausea; treatment includes pilocarpine eye drops, oral or intravenous acetazolamide, and intravenous mannitol.

Mycoplasma pneumoniae is a leading cause of a community-acquired respiratory illness occurring in children with manifestations occurring throughout the year but peaking in summer and early fall. Predominantly affecting school-aged children, the infection presents as pneumonia, featuring fever, cough, dyspnea, and sore throat. Extrapulmonary manifestations such as Stevens-Johnson have been rarely associated with mycoplasma pneumoniae infection presenting with ocular, oral, and genital involvement.

In this article, we discuss Ye 's recent article on the association between age at diabetes diagnosis and subsequent risk of age-related ocular diseases. The study, which utilized United Kingdom Biobank data, highlighted a strong link between early diabetes onset and major eye conditions, such as cataracts, glaucoma, age-related macular degeneration, and vision loss, independent of glycemic control and disease duration. This finding challenges the previous belief that diabetic eye disease primarily correlates with hyperglycemia.
