Diver Loses Distance Vision After Innocuous Dive
A young diver develops temporary nearsightedness (myopia) after repetitive, shallow, no-decompression air dives.
Diving Incident Reports Post Type
A young diver develops temporary nearsightedness (myopia) after repetitive, shallow, no-decompression air dives.
Problems with pressure equalization in the middle ear are very common in diving and may result in barotrauma, which is the most common diving injury.
This is a very rare injury, but diligence and forethought will likely reduce the occurrence. Do not underestimate the energy released with the rapid expansion of compressed gas.
With any injury in the marine environment that penetrates the skin, medical evaluation and treatment are essential. Documentation indicates that seal bites in particular have a very high probability of infection.
A diver develops a postdive skin rash and weakness 30 minutes after eating a lobster sandwich. He was treated successfully, but the symptoms reoccurred with diving.
This painful incident described by the diver is an example of barodontalgia, which is defined as pain or injury affecting teeth due to changes in pressure gradients.
This diver’s symptoms are consistent with skin manifestations of decompression sickness (DCS). With the additional coughing (the chokes) and an episode of loss of consciousness, it is very likely that a neurological component was present.
To help alleviate pain and symptoms, a diver was treated via in-water recompression. However, the pain did not subside and later manifested as spinal decompression sickness.
There were plenty of warning signs for this diver. He probably had difficulty climbing a few steps of stairs in everyday life, and that is sufficient indication of poor physical fitness.
Considering the reportedly moderate exposure and the absence of provocative factors like breath-holding or rapid ascent, a paradoxical embolism through a patent foramen ovale (PFO) could have been a contributing actor.
