RESUMO
We here report a case of scleral buckle infection with fulminant scleral abscess secondary to Moraxella species. A 54-year-old chronic alcoholic male with a history of retinal detachment repair, with scleral buckle 8 years prior, presented with complaints of severe pain, redness, and swelling in the right eye since 2 weeks. The patient was diagnosed with scleral buckle infection, the buckle was removed, and cultures revealed Moraxella species. The postoperative course included fulminant scleral abscess treated with dual antibiotic therapy that included ceftriaxone and moxifloxacin. All systemic antibiotics were discontinued after 3 weeks, retina remained attached, and no recurrence occurred over a 1-year follow-up. Moraxella, though commonly associated with bacterial keratitis, can also lead to buckle infection, especially in chronic alcoholic and immunocompromised patients. In buckle infection, infected buckle along with sutures should be immediately removed without damaging underlying compromised sclera. Lastly, culture and drug sensitivity play a very important role in buckle infections.
RESUMO
Oculocutaneous albinism is characterized by partial or complete absence of melanin in retinal pigment epithelium (RPE) and uveal melanocytes. Absence of typical fundal background from RPE and choroid makes it difficult to diagnose retinal disorders in ocular albinism. Lack of melanin in RPE makes the laser photocoagulation very challenging in these cases. This report presents a unique case of preterm infant of oculocutaneous albinism diagnosed as aggressive posterior retinopathy of prematurity (APROP), which was successfully treated with diode laser photocoagulation. The parameters of the laser used in this case were higher than usual, just enough to achieve blanching of retina. This report highlights the fact that the diagnosis of APROP and its treatment with laser is challenging in the presence of oculocutaneous albinism, but it is possible to achieve complete regression using diode laser at higher parameters.
