A case is presented of a retained Descemet's membrane after penetrating keratoplasty, highlighting the importance of the anterior segment optical coherence tomography (OCT) in the diagnosis and treatment planning of keratoplasty complications. A review of literature is also presented. An 88 year-old man underwent penetrating keratoplasty for bullous keratopathy. A retained host Descemet's membrane was detected. The retained membrane went unnoticed until the visual acuity decreased. The ophthalmological examination showed the presence of an opalescent membrane located below the endothelium, and was identified as the Descemet membrane of the receptor. Nd:YAG laser membranotomy was performed after the diagnosis. To conclude, it is noted that the inadvertent retention of the host Descemet membrane is a rare complication in penetrating keratoplasty. The anterior segment OCT was used to determine the diagnosis, and Nd:YAG laser membranotomy is an indicated treatment in these cases.

Michaelis-Manz syndrome is an autosomal recessive hereditary tubulopathy associated with mutations in the tight-junction proteins claudin-16 and claudin-19, which are present in the distal convoluted tubule and the loop of Henle in the kidney. Claudin-19 is also expressed in the retinal pigmentary epithelium. The clinical picture causes hypomagnesemia, hyper-calciuria and nephrocalcinosis that can lead to renal failure, which is the condition that marks the prognosis of the disease. Ophthalmologically patients can present macular coloboma, myopic staphyloma and nystagmus. We present the case report of an 18-year-old man suffering from hereditary hypomagnesemia, hypercalciuria and nephrocalcinosis, or Mich-aelis-Manz syndrome, with macular coloboma and stable visual acuities. Keywords. Hypomagnesemia. Hypercalciuria. Nephrocalcinosis. Macular coloboma.

OBJECTIVE: To report a case series of external ophthalmomyiasis in a region of Spain together with its common epidemiological factors and treatment. MATERIAL AND METHODS: A presentation is made of four clinical cases of patients with external ocular myiasis caused by Oestrus ovis larvae. RESULTS: Ocular myiasis is a parasitic infection by larval stages of flies. It can affect the ocular globe externally and / or internally, with the former being the most frequently found condition. The organism that mainly affects the eyes is the Oestrus ovis larvae. CONCLUSION: Ocular external myiasis is a rare condition that occasionally can occur in humans. In this case series, a common risk factor for infection is established: the previous exposure to livestock and / or agricultural activity. An adequate diagnosis and treatment could avoid the transition from external to internal form, as well as its complications.
